Hello
This is David Pyo ,new member from Melbourne Australia.
I have Catana 474 catamaran with hydraulic steering system.
I had desynchronize problem badly. I did change two piston(ram) port and starboard, and breath air myself many times.
But the problem was still there,
So I added cable system to tie the rudders together on the top of hydraulic system.
This time it works !!!!!! Now I only synchronize once a week.
some how I still believe that hydraulic rudder steering system should work by itself.
Anyone who have same experience, or Know how to improve hydraulic steering system in catamaran
please write some advice
Cheers
David Pyo
